Iconifying and Maximizing a frame in Java

In this section, you will learn about the Iconifying and maximizing a frame in java. Iconifying means to show a frame in minimized form. This program displays a frame in both forms. By default the frame will be in the minimized form. Following is the image of the frame which has to be minimized or maximized:

This is normal window which has to be maximized

Code Description:

frame.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG):
The setWindowDecorationStyle() is the method of the JRootPane class which sets the window decoration type using the constant property PLAIN_DIALOG of the JRootPane class.

setExtendedState():
It sets the state of window to minimize and maximize. It uses the constant field of the JFrame class.

MAXIMIZED_BOTH
This state is used to maximize the frame horizontal and vertical.

ICONIFIED
This state checks whether the frame is minimized or not.

Here is the code of program:


import javax.swing.*;



public class IconifyAndMaximizeFrm{

  public static void main(String[] args){

  JFrame frame = new JFrame("Iconifying and Maximizing a Frame");

  frame.setUndecorated(false);

  frame.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG);

  frame.setExtendedState(JFrame.MAXIMIZED_BOTH);  //Maximizing the frame

  frame.setExtendedState(JFrame.ICONIFIED | frame.getExtendedState());

  //Minimizing or Iconifing the frame

  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

  frame.setVisible(true);

  }

}
